Summary REGRESSION(r25547): With Hanin IME, one cannot input characters into forms

Reported 2007-09-19 06:59:32 PDT
With r25634, one cannot input text into forms after Hanin is activated. English/US -> Sucess English/US -> Hanin -> Fails English/US -> Hanin -> English/US -> Fails The problem seems be triggered by Hanin's method of English/Chinese input mode switching via the Caps Lock. After one switches for once, the input no longer works.

I can't repro this bug, exactly what are you doing? eg. what letters are you typing, what is the output, and what should the output be?

1. Open any page with a form. 2. Starting typing with Hanin If at this point, you press enter, correct Chinese characters will appear. Type more into the staging area and press backspace to correct the input, the cursor and the staging string will disappear and no longer will you be able to input anything with any IME including English/US.

More detailed info on the bug. Hanin has 2 correction modes, phonetic and per character. This symptom is very significant when the correction mode is set to "delete character". When set to "revert phonetics", sometimes it works, but backspace key would sometimes cease to function.

I see a very similar issue with RuSwitcher - pressing Backspace several times (deleting the whole inline input area) makes further input impossible.

Using hanin input, i type abc -- i get a single character that changes I hit enter i type another set of characters (still results in a single changing character) I hit backspace At this point i can type again, but the arrows keys won't work, hitting enter doesn't free the caret but if i type a character an hit enter, that will free it. Is this what you are seeing?

Bug was due to r25547 introducing new and cleaner code, which unfortunately did not clear the composition markers when they defined a 0 length region. Sending WebCore/ChangeLog Sending WebCore/editing/Editor.cpp Transmitting file data .. Committed revision 25694. Reporter: please confirm against r25694 or later

The problem I saw with RuSwitcher (comment 6) is fixed. I haven't tested Hanin.
